WebAn inhibitor may bind to an enzyme and block binding of the substrate, for example, by attaching to the active site. This is called competitive inhibition, because the inhibitor “competes” with the substrate for the enzyme. That is, only the inhibitor or the substrate can be bound at a given moment. WebMar 14, 2024 · The inhibition of cyclooxygenase activity by aspirin is due to its ability to chemically modify a serine residue (Ser530) of the enzyme.
